SmartStock Accuracy tuner, anyone have experience with it?

[Texas10]

Interesting idea http://www.stocks-rifle.com/smartstock.htm

Click on the rifle to see how it installs in the stock.

It's a movable pressure point under the barrel. Acts as a harmonic tuner.

Just curious.

Really no different than Ruger's pressure point in their stocks (M77 series), or a BOSS system, or the rubber doughnut. They all can/do work, but need fiddling with, and different loads change the need typically.
Personally if a tuner is in your wheelhouse, I would prefer the Rubber deal.

MZ5 was fooling with various pressure points(not this system, but same notion) some time ago. I know he got some good results, but back to the change of components(bullets, lot # of powder, etc) and he abandon it.
